我在 ie7 上的 ajax4jsf 库有问题，它给我错误“A4J 未定义”，但该错误未出现在 Firefox 和 chrome 上

我使用 myfaces1.1.5 和 ajax4jsf1.1 的库

这是我的web.xml：

我们有一个集群环境，IHS 将流量引导到两个节点。部署未与一个节点正确同步，导致间歇性出现 a4J 未定义错误。重新启动节点和服务器，应用程序开始正常工作。

XYZ 未定义。

这是一个典型的 Javascript 错误。因为它在真正的网络浏览器中运行良好，所以服务器端的一切都很好。

只有想到的是使用/生成的javascript库中的冲突。我建议升级到可用的最新版本并全力以赴。
